The front and rear adjustment plates 3 of the ejector rod are arranged at the lower part of the pressure rod 1; 151, the screw 152 is connected to the ejector screw plate 151; the ejector rod 10 is connected to the screw 152;

Described planar main board 8 is fixedly connected with guide shaft 5; Described guide shaft 5 is connected with protective plate 16; On described protective plate 16, connects positioning plate 6 by spring 17; Described positioning plate 6 is provided with There is a groove 61; the positioning plate 6 is located under the ejector screw plate 151;

A test thimble 81 is provided on the planar main board 8, and the test thimble 81 communicates with the groove 61; the test thimble 81 is connected with the test equipment.

The jack screw plate 151 is fixed on the jack fixing plate 15 through a sliding connection.

The protection board 16 is fixedly connected to the plane main board 8 through the positioning pin 7 .

The spring 17 is arranged on the guide shaft 5 .

The pressure rod 1 is fixedly connected to the pressure rod support column 14 by using a screw 2 .

The utility model realizes the rapid replacement of the protective plate 16 and the positioning plate 6 by designing the protective plate 16 to be fixed by the positioning pin 7; After being too short, there is no need to replace the ejector rod 10, only the length can be adjusted by rotating the screw 152, and the ejector rod 10 can move back and forth, left and right, and can be loaded and unloaded for adjustment.

To sum up, the structure of the utility model adopts an adjustable design, which is convenient and practical to operate, can save a lot of fixture manufacturing time and material costs, and improve production efficiency at the same time. It is a practical universal fixture for battery testing.
